Atmel AT16646F
The Bus Hold feature eliminates the need for pull-up or pull-down resistors and retains the last active state during a Tri-State event. The data output functions may be enabled or disabled by various signals at the xOE or xDir inputs.| Part No. | AT16646F |

DESCRIPTION
Atmel’s AT16646 devices are 16-bit high speed, low power Tri-statable D type registers, ideal for use in systems requiring both transparent and registered mode functions. They are organized as two separate 8-bit bus transceivers. Data flow is bi-directional, and can be controlled for multiplexed transmission between A bus and B bus either directly or from the D registers by use of the direction control pin (xDir), output enable (xOE), and select lines (xSAB and xSBA). Storage of data on the A bus and B bus is controlled by the output pins. They have very low ground bounce and excellent input noise rejection, giving the user stable signals in a high speed environment.
